Finite Element Simulation for Laser Deposition Process of Graphite Copper Gradient Composite of Thermal Stress

Abstract:

Taking account of the special structure of gradient material and take advantage of good toughness properties of copper,Based on Ansys secondary development technology, using the Gauss moving heat source and the element birth and death technology, a laser direct deposition of graphite copper gradient composite thermal coupling model was developed;On the basis of accurate calculation of the stress field,the generation mechanism of crack in layer by layer and transverse crack and longitudinal crack for the deposition parts was revealed.
